wifi是我们在手机中必须连接的一个APP,因为如果一个智能手机没有连接wifi很多功能都无法使用,也无法给我们带来乐趣,但是我们在连接wifi的过程中,大多数人都会遇到,手机wifi已经显示连接上了,但是还是无法打开网页浏览网络!
看来wget之前也存在此类问题,于是继续搜索标准,输出如下:The presence of a message body in a response depends on both the request method to which it is responding and the response status code . Responses to the HEAD request method never include a message body because the associated response header fields , if present, indicate only what their values would have been if the request method had been GET . 2xx responses to a CONNECT request method switch to tunnel mode instead of having a message body. All 1xx , 204 , and 304 responses do not include a message body. All other responses do include a message body, although the body might be of zero length.
